" attle, in the county of King and State of "Washin ton, have invented certain new and useful sniprovements in Conveyors, and do hereby declare the following to be a full,

clear, and exact descri tion of the invention,

such as will enable 0t iers skilled in the art to which it appertains to make and use the some.

This invention relates to portable conveyers, and partichlarly to the endless belt tyne.

of a conveyor capable of being adjusted readily to. an desired position and firmlyand rigidly held in position during operation.

With this and further objects in view, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

Referring to the drawings b numerals, 1

indicates the framework of t e mainmonup "of angle irons and T-irons and constitutes the support for the conveyor .mechanism hereinafter specifically described. The said framework .1. at its lower end pivotally engages the shaf t .2 which extends transversely of and is carried by the truck 3.

The truck is made up of a platform or frame 4 which pivotally supports the framework 1 so that the said frame or platform 4 is not bodily movable independently of said frame, and may therefore be considered as the fixed platform. The said fixed platform 4 is mounted'on suitable casters 5 and is engaged'by a telescoping or longitudinally movable platform or framework 6, which latter platform is preferablysustained bysuitable casters 7. The sides of'the latforms 4 and 6 are 1pgeferably made of 21115 e irons arranged veyer which framework is preferably made the shaft 11 and the se eee inclosing't'n'e angle irons of the sides of frame 4. 2; S1llh&l1l8 clamping plates 88 are arranged to inclose t ie overlapping portions of the sides of frames 4 and 6 best-seen in Fig.

20. A bolt 9 is threaded through each of the galeanpin plates 8 in position for clamping the over a ping sections together when the bolt is tig itened by means of a rod or other suitable handle 10 connecting to the outer end of the bolt. In practice, the platfprm 6 brackets depending from the rear end of the ,i'ram'e 6 and is provided with fixed drums til-12. Cables 1313 are fixed at their inner ends to the shaft 2 and extend rearwardly and are passed about the drums 12 and was pod about the same, and then extended orwardly again and passed about block 14 suitably supported by the forward end of the platform 6. The cables extend past the said blocks and are connected to eyes 15-15, fixed to the rear ends of the sides of frame 4. provided with a ratchet-wheel 16, engaged y a pawl. The shaft is adapted to be engaged-by any suitable operating tool 18, and when rotated by said tool in one direction takes in one portion of the cable 13 for drawing the platform 6 forwardly, the portion of the cables beyond the drums 12 being paid out at the same time, which accommodates the movement of the frame 6 with respect to frame 4:, with regard particularly to the con-- nections of the cables to the eyes 15. When it is desired to force the frame 6 rcarwardly, it is only necessary to reverse the rotation of ortions of cables 13 which enga e the shaft 2 will be paid out while the ot crportions of the cables will be taken in, such taking in of the said cables causing the cables to exert a drawing force on the eyes 15for causing the block 14 to travel towards such eyes. This will prod ucc an outward movement of platform 6. In order to prevent thc'castcrs 7 from pivoting undesirably, the said casters are inclosed by suitable frames 16, the frames being connected by links 17-17. The front link 17 is engaged by cables 18--18, which extend to and are connected with drums 19:19 fixed to a shaft 20 carried by the frame portion 4. The shaft 20 is preferably rovided with a ratchet-wheel 22 engaged y a suitable pawl 22 for preventing undc- 1 sirable rotation of the shaft. The shaft may be provided with any suitable operating a means, asindicated in Fig. 19.

The shaft 11 is preferably Pivoted to the latforin 6,. as at 23, on opposite sides of th s platform are standards 24, .MWhich are adapted to be swun to and from a vertical )osition. When disposed vertically the said standards are directiy above the casters 7 so that said casters die rectly support the weight sustained by said standards 24.

In order to insure the operation of the convcvcr, andto positively prevent accidental collapse I preferably provide brace bars 26, one arranged at each side of the platform 6, and each connected at. its lower end to a bracket 27 projecting upwardly from one of the clamping plates 8, and at the upper end to a bracket 28 extending from the respective standard 24. The connections of the braces 26 are such as to facilitate ready removal of the braces and consist preferably of bolts assed through the respective brackets and )raccs and retained in place by cotter ins.

Each standard 24 is preferably provided with a longitudinal slot 29, and a shaft 30 extends transversely through said slots and projects beyond the outer face of said stand ards. Each projecting end of the shaft 30 extends through a depending bar 31. of a pulley casing 32, said ulley casin inclosing a pulley 33 arrangerf beneath ifferential pulleys 34 suspended from the upper end of the respective standards. The iffcrential pulleys 34 are of the ordinary type, as seen, best in Figs. 8 and 9.

(iii crential pulleys 34- and downwardly about the pulley 33 andagain' u werdly about the smaller of'the differentia pulleys 34, and again downwardly. The chains 35 are thus arranged to operate in the ordinary manner in conncctionwith the well-known form of differential pulleys and maybe mu atcd for raising and lowering the shaft 30. and when not being operated the chains will sustain the shaft 30 in any given position.

For the purpose of retaining the shaft 36 in its position with respect to the bars 31, a suitable nut 36 is threaded onto each end of said shaft, and is preferably provided with an operating handle for facilitating grip ing the 11:.

respective plate 31 and releasing t e same when desired.

In operation, the framework 1 extends between the standards 24 and rests upon the shaft 30, suitable bearing plates 37 being ar- 12\ may be swung upon its pivot vertically by An endless chain 35 is passed upwardly about the larger of the me At the lower; end of each plate 37 is 12a;

access sci-us tion of the chains 35, and the up er end of the frame thereby raised or lowere to the.

It will be further noted required extcnt-.

movement of the shaft that if the extreme through the operation of the chain is not suliicient, the platform 6 may be moved in i one direction or the other for causing the The hooked bars 39 mgly engage each of the side bars shaft- 30 to move along the wearing plates 37 and tl'iereby elevate or lower the up or end of the frame 1, according to whet er the platform 6 is moved forwardly or rearward ly depend from and slidol the platform 6 and the opposite bars 39'are connectedby cross bars 40 arranged for sustaining a preferably electric motor 4 1, to the shaft of a sprocket wheel 42 about which is fixed which is passed a sprocket-chain 43 which extends to and is essed about a driving sprocket wheel 524 'ed to a shaft 45'journaled in bearings 46--46 in the-frame 1.

imme 1 "being accommodated as far as, the

chain 43 is concefnedby sliding the support for the motor d1 longitudinally of the pletform 6..

The shaft 45 is formed with a longitudinal groove 48 for receiving the spline of asprocket wheel 49, The wheel 49,1s formed with a suitable hub 50 through which is threaded 51 into engagement with the the set screw shaft 45 for locking the sprocket -49 in osition on said shaft, said sprocket being adiipted to be adjusted longitudinally of the shaft 45. A sprocket 52 of less diameter is fixed its low speed, or the said chain may journa-led in the to or formed integral with' the sprocket 49'. Spaced longitndinall of the frame 1 from the shaft 45 is a shalt 53 which is journaled in suitable bearings 5454.mounted in said frame, and fixed to the shaft 53 are s rockets end 56,-the sprocket 55 being of less diameter than the s rocket 56. Ashaft 57 is aniework 1 between the shafts 45 end .53 and carries an idler pulley The journals of the shaft 57 find bearngs in bearing boxes59 whichare suppeto, by longitudinally adjustable screws 4 60, whereby the pulley 58 may be adj asted vertically for taking up the slack in the chain 61 which is passed about either of the sprockets 49 or 52 and one of the sprockets 55 or 56.

in practice, the chain 61 may be positioned to connect sprockets'52 and6 for securing be caused to connect sprockets 49 and 55 for secnnng high speed. If an intermediate speed is. desired, the sprockets 49 and 62am shifted longitudinally of shaft 45 until the sprocket 52 the wood se ments,

is brought into slinenient with sprocket 55 and the chain 61 is passed about thesprockets 52 and 56 for transmitting power from shaft 45 to shaft 53.

The shaft 53 carries a fixed pulley 62 about which is sssed a driving belt 63 which belt extends I 'ongitudinally of the framework 1 and is passed about the drum or pulley 64 at the upper end of "the framework. The pulley 64 is of special construction, as best seen-in Figs. 10 and 11. End plates 65 are provided and are formed with a plurality of at peripheral faces 66 strengthened by any suitable number of radial webs 67. Projecting upwardlv' from each of the said flat faces are suitable pins 67-67, and the said plates 65 are connected by segmental memers 6868 which are preferably formed of wood for convenience of renewal and for cushioning theioperation of the parts. The

. pins or lugs 66 project into the segments 68 held in position passed through 66 and through and the segments are further by bolts 6969' which are the material of the flat faces -the segments, the outer ends of the bolts 69 against pulling through b the provision of a metallic band 70 at eac end of the policy 64 through Which'the bolts 69 are passed.

Arran ed Within and intermediate the length 0 the segments 68 is a pair of plates being preferably held 71--7 1 of similar construction and arrnngement to plates 65 and provided with projectmg lugs or pins 72 correspondin in arrangement to'the lugs or pins 67 of t e lates 65. Thewebs 71 are connected centrally ya. hearing thimble 73 which is arranged in al'inernent with the corresponding thimblcs 74-44 oi" the plates 65, said thirnb'le being designed to receive a shaft 75;vhichhas its projecting ends suitably journaled iii the framework 1,

suitable set screws for lockingthe plates 65 respective segments 68 are formed with a transverse notch so-positioned that when the segments are assembled for producing the drum 67 a circumferential groove 77is roducedand is arranged for receiving the riving belt 63 so that the outer surface of said driving belt will lie flush with the periphe of the groove. The drum 68 is thus left wit a smooth continuous surface for the recep-- ties )f the load-carrying belt 78. In or; r to compel the driving belt 63 to acconimodste itself erfectly to the groove 77,0ne is of the bel t is engaged by an idler 7Q carrie by a'shaf; 80 jourcal'e'd at its ends in jburnal boxes 81. The journal boxes 81 are mounted' to slide transversely of the framework 1 and are engaged by screws 82 adapted to adjust said boxes for taking up theslack in the belt 63 The said idler 79 prevents the belt from having any undesir' able vertical movement and keeps the same snugly in'place against the drum 64. It will 76-7 6 are provided. tothe shaft 75. The:

movement. The pulle s 83am preferabl of the grooved type an the edges of the be t I 63 lie within the rooves of said pulleys so that the pulleys ay up and down with any slight vertical vi ration of the belt while retaming the belt absolutely against edgewise play. fiuitable washers 86-86 may be fixed upon the shafts 8 1 above and below the pulleys 83 and spaced a short distance therefrom for limiting the vertical movement of r the pulleys.

The shaft 75 of the drum fi l/is 'ournaled injournal boxes 87 arran ed to all e longitudinally of the framewor. 1 and'engaged by screws 88 for adjusting said journal boxes for taking up slack in the carrying belt 78, the said belt extending from. the drum 64 to the opposite end of the framework and about a drum 89 siihilar in construction and arrangeinent to drum 64, except that it is not.

provided with an annular groove for the re ception of the driving belt. The drurn89 is fixed to the shaft 90 journaled in boxes 91 mounted to slide longitudinally of the=fra1ne 1 and engaged by screws 92 for purposes of adjustment, whereby the slack in the belt 78 maybe taken up. The belt 78 may be of any ordinary type, but by preference it is rovided withbrackets 93 -93 at suitable intervals for engaging the material to be conve ed, preventing the slipping of the same ongit udinally of the belt. The carrying surface of the belt extends above the up- -per surface of the framework 1 and is supported by a series of pulleys 94 and the rcturn la of the belt passes beneath the belt 63 an moves longitudinally within the frame 1 above the lower surface thereof. Longitudinal heads or slats95-l)5 arc carried by the lower transverse braces of the framework 1 in iosition for supporting the return'lap of the belt 78. The saidbeads )5 ate preferably half-round in transverse section and are usually formed of wood, the rounded surface being, uppermost for being engaged by the belt. Near the lower end of the framework 1, preferably below the driving mechanism, is arranged an idler 96 which engages the return lap of the belt 78 for retaining the same in proper relation to eeaese the drum 89. The said idler 98 is mou'hted' upon a shalt 97 which is ournaled in. boxes 98 mounted to slide transversely of the framework 1 and engaged by screws 99 for facilitatingany desired adjustment thereof.

At any suitable points along the length of the frame .1, and. particularly near the ends thereof, 1 provide pulleys 100 which engage the edges of the carrying la of the belt 78 and prevent any edgevnse p ay of said belt. 7-

bolt 101 go Objectionable undulating movement of the g5 belt which sometimes occurs, is obviated by the use of the pulleys 109.

The pulleys or rollers 94 are preferably of a length equal to or greater than the width of the belt 7 8 and each of said rollers is car- 99 ried by a shaft 102 journaled in a suitable bearing box at each end upon the upper edge of the name i. The hearnl 'boxes I01 each e of the chairs r02 are of special construction,

as will beseen from Fi e. 12 to lll hiclusive. 95

Each of said boxes consists of a 'base 103;, formed with a semi-annular notch or recess 10% arran ed intermediate its length. At each end t e base 103 is provided a bolt-receiving aperture 105. Preferably centrally 10 of the recess or notch 104 is. arranged an upwardly extending tooth or in 106 for pun poses hereinafter specified n connection with the base 103 a cap or closure is em ployed, consisting of a semi circular plate 107 provided with laterally extending lugs 108-108 apertured at 109 for registering with apertures 185, so that a retaining bolt may be passed through the apertures 105 and into the framework lor retaining the bearing plates in osition. A tooth. or in llt de pends pre 'erably from the center or the plate 10? so as to be by preference in alinement' with a tooth or lug 106. A thimble orsleeve 111 is arranged to be interposed. between the plate 107 and the base 103 when the partsare assembled as indicated in Fig. 24: The thiinhle 111 provided with transverse apertures 112v 112 positioned for receiving the lugs 1G6 and 1.10, whereby the said thin":- ble is positively locked against movement when positioned between the plate 107 and the base 103. The thinible 111 is provided with a lon 'itudirial bore adapted to receive the j ourna end of the respective shaft 102.

As best seen in Figs. 1 and 17, l contemplate providing an auxiliary conveyer for de ivering; the goods to belt 78, which may be considered the main 'conveyer belt.

said auxiliary e-onveyer is made up of a frsrnef 113 supported on casters 11 1, the said casters being arranged on opposite sides and intermediate the length of the frame so as to produce a, truck capable of being readily shifted its desired. In operation, the forward end of the frame 113 may rest upon the ground or flooring, and when it is desirable toshift the irernc.the same may be elevated and moved upon the casters 114.

The shaft 90 of drum 89 as clearly seen in Fig. 17,' extends beyond its bearings and is provided at each end with s flanged sprocket 115 engaged by e s rocket chain 116 extendmg to a corres on he, sprocket 117 fixed to the corres'pon gly pro ectin end of a shaft 118 journaled in the end 0 the auxiliary frame 113 contiguous to the main conveyer frame 1.. The two sets of s rockets 115 end 117 and chains 116 areemp oyed in order to provide on evenly-bslsnced driving mechanism, although it will be obvious that only one set of ssidisprockets and one chain may be employed, if desired. The shaft 118 is journeledin boxes 119 mounted to slide longitudinally of the framework 113 and is engaged by a screw 120'101' adjustment 01' said j ournsl boxes when it is desired. Spacing bars 121 are arranged on the opposite sides of the framework 113 and connect the respective journal 'b'oxes 119 with the corresponding journal boxes 91 the said bars 121 thus maintaining the chain 116 in, s taut'condition. Each of" the bars 121 may be provided with a turn buckle 122 for taking up ellsleek inthe chain 116'. The shaft 118 carries a s'uitoble'dri drum 123, eboutivhich is passed a carrying belt 124"similar inconstructionand arrangement to belt 78, the said belt 124 being passed about a drum 125 zit-the lower or forward end of the frame 113 end being so ported by the pulleys or rollers l vid'cd with sdiustable journa.
